Amazon Ads Audit: Find Wasted Spend in Under an Hour (2026)

Pull your last 60 days of Amazon ad data right now and there's a good chance 15-25% of that spend went to clicks that never had a real shot at converting. That's the number we see across the accounts we take on. Not because the sellers are bad at this. Because nobody ever sat down and ran a real Amazon ads audit.

You don't need software for this. You don't need to hire anyone yet. You need six reports, a spreadsheet, and about 45 minutes. Here's exactly how to run an Amazon ads audit yourself, in under an hour, using only what's already inside your Seller Central and Advertising Console access.

If you finish this and decide you'd rather have someone else do it every month, that's a different conversation. This post is the version you run today, on your own, for free.

Why a Blended ACOS Number Is Lying to You

Most sellers check one number: overall ACOS. If it's under 30%, they assume things are fine. That number is an average across campaigns that have nothing in common. A branded campaign running 6% ACOS and a broad-match discovery campaign running 55% ACOS can blend into a "healthy" 25% average while one of those campaigns is bleeding cash.

An audit exists to break that average apart and look at each piece. That's the whole exercise. Six specific checks, each one isolating a different kind of waste.

For the architecture behind why campaigns should be separated this way in the first place, see how we structure PPC campaigns across 85+ brands. This post assumes your account already exists in whatever state it's in and shows you how to find what's wrong with it today.

Step 1: Pull the Search Term Report and Cut the Dead Weight (10 minutes)

This is where most of the waste lives. Go to Advertising Console, pull the Search Term Report for the last 60 days, and export it.

Sort by spend, descending. Now look at every search term with 15 or more clicks and zero orders. Not "low conversion." Zero. These are terms Amazon's algorithm decided to show your ad for, shoppers clicked, and nobody bought. That click cost you real money and taught you nothing new.

What to do: Negative-match every one of these terms at the campaign or ad group level today. Not next week. This single step, on a typical account we audit, recovers the single largest chunk of wasted spend of any item on this list.

A second pass worth doing while you're in this report: look for search terms that are converting well but sitting inside an auto or broad match campaign. Those terms should be promoted into their own exact-match campaign with a higher bid. You're currently underpaying for your best traffic and overpaying for your worst, in the same campaign, at the same bid.

Step 2: Break ACOS Out by Campaign Type (10 minutes)

Pull your campaign performance report and group campaigns into three buckets: branded, category (non-branded), and competitor targeting. Calculate ACOS separately for each bucket.

The ranges that matter:

| Campaign Type | Target ACOS | What It Means If You're Outside It | |---|---|---| | Branded | Under 10% | Above 15%: something is broken. This should be your cheapest traffic. | | Category / Non-branded | 18-35% | Above 40%: broad match is bleeding budget on discovery that isn't converting. | | Competitor | 30-40% | Above 50% with no improvement in 60 days: cut it. |

If you've never separated these, do it now. A blended 24% ACOS could be a branded campaign at 8% carrying a competitor campaign at 55%. You'd never see that in the aggregate number. It's the single most common thing we find when we take over an account: the seller genuinely believed their ads were fine because the top-line number looked fine.

Step 3: Check Branded vs Non-Branded Spend Allocation (5 minutes)

Total your branded campaign spend as a percentage of total ad spend for the last 60 days.

It should land at 10-15%. Two failure patterns show up constantly:

Branded spend over 20%. You're paying to defend traffic that, in most categories, would convert at a similar rate organically anyway. Branded search is the cheapest traffic you'll ever buy, but overspending here still means you're spending more than you need to on demand that already exists.

Branded spend near zero. This is the quieter problem. If you're not running branded defense campaigns at all, a competitor can bid on your own brand name and intercept shoppers who typed your name into the search bar specifically to buy from you. We've seen this on accounts brought in from a prior agency more than once: a competitor's ad sitting above the brand's own organic listing, on a search for the brand's own name, for months, because nobody was watching.

Step 4: Review the Placement Report for Bid Mismatches (10 minutes)

Pull the Placement Report. This shows performance broken out by Top of Search, Rest of Search, and Product Pages.

Compare your placement bid adjustments (set at the campaign level) against what the data actually shows. Top of Search typically converts at the highest rate but costs the most per click. Product Pages placements are usually cheaper with lower but still real conversion. Rest of Search sits in between.

The check: If you have zero placement bid adjustments set, you are letting Amazon's default weighting decide where your budget goes instead of directing it toward what's actually converting. If you do have adjustments, confirm they still match current performance. Placement performance shifts over time as competitors adjust their own bids, and an adjustment set six months ago may no longer reflect what's winning today.

Step 5: Check for Dayparting and Budget Pacing Gaps (5 minutes)

Look at your campaign-level daily budgets against actual daily spend for the last two weeks. Specifically: is any campaign hitting its budget cap before noon on more than two or three days?

If yes, you're losing afternoon and evening impression share entirely. Amazon stops serving your ads once the daily budget is spent, so a campaign that caps out at 11am is invisible for the rest of the day, including hours that may convert better than your morning traffic.

Two fixes, pick based on the cause:

• If the campaign is genuinely capped by an underfunded budget on strong-performing keywords, raise the budget.
• If the campaign is spending fast because of a specific high-traffic, lower-converting hour (common with impulse browsing late at night), add dayparting to pull bids down during that window and redirect budget toward hours with better conversion.

Most sellers running standard campaigns have never touched dayparting. It's not required to run ads, but it's one of the more direct fixes once you can see the hourly pattern.

Step 6: Audit Negative Keyword Coverage (5 minutes)

Check whether your auto and broad match campaigns have an active, maintained negative keyword list. Then cross-reference against the search term report you already pulled in Step 1.

Any search term that appears repeatedly with clicks and zero conversions, and isn't already on your negative list, is a coverage gap. This is different from Step 1's one-time cleanup. This check is about whether you have a system, or whether you did a cleanup once and let it drift.

The habit that fixes this permanently: review the search term report weekly, not quarterly. Search intent shifts, new irrelevant terms creep in constantly, and a negative list built once six months ago is already stale.

The Red Flags Scorecard

Score yourself against these seven items. Each one you check off is a specific, fixable leak, not a vague sense that "ads could be better."

1. You only look at blended ACOS, never broken out by campaign type
2. No negative keywords added in the last 30 days, even though the account is actively running
3. Branded campaign spend is over 20% of total budget
4. Zero placement bid adjustments set on any campaign
5. A campaign has hit its daily budget cap before noon on 3+ days in the last two weeks
6. You're running a single campaign per product instead of separate campaigns by match type and intent
7. No dayparting, even though hourly performance clearly varies

0-1 flags: Your account is in reasonable shape. Keep the weekly search term review going and revisit this audit quarterly.

2-3 flags: You have real, recoverable waste. Most of it is fixable in an afternoon using the six steps above.

4+ flags: The account needs more than a cleanup. At this point you're usually looking at a structural rebuild, not a tuning pass. This is the point where doing it yourself starts costing more in lost time and lost spend than having someone rebuild it properly.

What This Audit Doesn't Cover

This is a spend-efficiency audit. It tells you where money is leaking inside the campaigns you're already running. It does not tell you whether your campaign architecture is the right shape to begin with, whether your funnel has structural gaps above and below your PPC layer, or whether declining organic rank is quietly forcing your ad spend higher every month.

If you run through this checklist and the numbers are ugly across the board, the deeper structural read is in the 7 gaps killing ROAS in a broken ads funnel. And if your ACOS looks fine but total revenue is flat or slipping, check TACoS against ACOS before you conclude the ads are the problem. A clean ACOS with rising TACoS means your organic foundation is eroding underneath campaigns that look perfectly healthy on paper.

How Often to Run This

Once isn't enough. Search terms drift, competitors shift bids, and a clean account six months ago accumulates the same waste patterns again if nobody's watching.

Weekly: Search term report review, negative keyword additions. Monthly: ACOS by campaign type, branded vs non-branded ratio, budget pacing check. Quarterly: Full placement report review, dayparting reassessment, complete run of this checklist top to bottom.

That cadence is exactly what we run across the 85+ accounts we manage directly. The checklist doesn't change. What changes is whether someone has the time to run it every week without it slipping.

If You'd Rather Have It Done For You

Running this audit once, today, will find real money. Running it every week, forever, is the actual job. That's where most sellers fall off. Not because the checklist is hard. Because it's one more recurring task competing with everything else running a business requires.

If you found more than a couple of red flags and don't have the bandwidth to fix and maintain it, get a free Amazon ads audit from our team. We'll pull the same six reports, plus a few we run internally that go deeper on organic rank correlation, and hand you a specific findings document within 48 hours. No pitch deck, just the data and what it means.

For sellers who want this handled on an ongoing basis rather than fixed once and left to drift again, here's how our Amazon management service works.

We share the specific waste patterns and fixes we're finding across client accounts every week in the newsletter. Worth a look if PPC efficiency is a real line item for your business.
